Being a light Anti-submarine Frigate, the Pr.35 '''''Mirka''''' class has very little substantial armour, with just 5 mm turret armour and the 15 mm splash guard for the forward turret. While these may minimize damage caused by small calibre HE rounds and splash damage from other areas being hit, they will not protect the turrets from direct fire starting at even the size of 12.7 mm machine guns. General survivability is not much better, as the primary armament is limited to two large turrets. Losing turrets is common on the Mirka and will result in your fire being halved at the least. Furthermore, the low crew count of 98 means that a very low damage threshold can be sustained on major components before the ship is destroyed. Thankfully the Mirka has a few aces up its sleeve to counteract these issues. To begin with, the crew are very spaced out in the ship, meaning that you will most likely survive the first few salvos. Secondly, because the hull has such a low freeboard for the majority of the ship, most of the machinery and ammunition is protected by the sea.

Mobility is a very strong suit of the ship. Starting at 57 km/h stock the ship lags behind destroyers and most cruisers, and cannot hold a candle to the late-game MTBs that it might face. However, of the Corvette/Frigate class, the Pr.35 has a distinct advantage, often holding a 10 km/h advantage or more over other ships of its size. These are rarely faced, however, and as such, it cannot be expected that you will ever be leading the charge in matches. The turn radius of the ship is reasonable, however, the initial snap can be very deceiving when initiating a turn. One major issue when manoeuvring the Mirka is the existence of the hull-mounted Sonar system. This dips far below the keel of the hull and can often be caught on rocks. Special attention must be given when manoeuvring around shoals and beaches where the Sonar might holdfast.

The primary armament of the Pr.35 is where the ship shines. It is armed with a pair of AK-726 76 mm semi-automatic gun turrets. Each of these turrets contains two guns firing a total of 90 rounds per minute. This firing rate allows for the ship to dismantle any opponent vessel in seconds, from MTBs all the way up to destroyer leaders and light cruisers. These guns have very nice post-penetration effects on targets lacking armour and can be extremely dangerous should you sneak up on someone. This firing rate comes at a price, however, and that price is two-fold. Firstly, the guns overheat quickly, barrages tend to be limited and the guns must be watched for overheat. Secondly, the shells have a relatively short range and their effectiveness drops off quickly beyond 5 kilometres when shells begin to miss and fire arcs become too great to regularly hit the target.

The Pr.35 "Mirka" is armed with a single quintuple 406 mm torpedo launcher armed with the SET-40 lightweight anti-submarine torpedo. The launcher has very good launch angles and five torpedoes are quite reasonable however that is where the praise ends. The torpedoes have only one operational setting, with no option for upgrades and are slow. At 54 km/h a cruiser with keen eyes can outrun these torpedoes and with 8-kilometre range, they are not going to reach much past the effective range of your turrets. Worse still the torpedoes have a meek 80 kg warhead, which will not destroy ships larger than a corvette in one hit. These torpedoes have limited use in surprising unsuspecting captains should you face something armoured such as a heavy cruiser, and can be used should the main battery fall silent, however, they are unlikely to destroy anything without multiple hits and must be used at a range where they cannot be avoided easily.

The Mirkas round off their armament with four RBU-6000 anti-submarine rocket launchers, each carrying 12 rockets to total 48. As being rockets they have a limited effective engagement range, high arcs of fire and are very hard to aim in conjunction with primary weapons, however should a small boat decide to get too close or should you decide to engage a target at point-blank range, the barrage of 25 kg warheads smashing into the superstructure and hull of the hostile ship will almost certainly cripple it, if not outright sink it.

=== Radar ===
 +
[[File:SKR-7-radar-view.png|thumb|Radar HUD tracking a target, with firing lead indicator, distance to the target, and closing speed visible.]]
 +
The vessel comes equipped with two radars:
 +
* MR-105 - tracking radar director, located on the main superstructure
 +
* Foot-N - search radar antenna, located on top of the mast
 +
They can spot targets at a significant range and provide a lead indicator, making it very easy to destroy aircraft using {{Annotation|HE-VT|High-explosive variable time fuse}} rounds, even at long range where the target might not expect accurate fire. By default, or after being destroyed and repaired, your radar may be turned off. You can turn it back on using the Switch radar search on/off control (default: {{key press|Alt|R}}). Be aware that if the target enters the blind spot behind the vessel, radar tracking (including the lead indicator) will be lost. In engagements with planes at distances smaller than 1 km, weapons tend to overshoot even when following the target indicator. Tracking will be lost at around 14 km, and at ranges of around 10 km or more, the lock will be very unstable. The detection range is over 20 km, including shells, missiles, and other munitions in flight. Radars have only one search mode available and do not provide any assistance in detecting or engaging surface targets.

The ''Mirka'' excels in close-quarter brawling with anything its shells can penetrate, especially in dispatching torpedo boats and early destroyers.  This vehicle is heavily reliant on both map and BR; it will crush 3.7 and below within seconds, but against ships of 4.7 and above will struggle heavily even within its gun range.  It is best not to spawn this vehicle on maps consisting of the open ocean unless you are left with no choice; due to its limited range the ''Mirka'' needs to exploit cover in order to close the gap without being targeted by guns with over twice the range. Critically, captains should avoid the wide-open ocean, as they will draw fire from targets that they cannot engage themselves.  Because the guns only fire HE, captains of the ''Mirka'' should avoid engaging cruisers, as they may find penetrating and damaging the components of cruisers difficult even in close quarters.

Captains of the ''Mirka'' should attempt to close the distance on any target and engage with their guns within 5 kilometres for maximum effectiveness, reserving torpedoes and rockets for extreme close quarters or emergencies. Prior to unlocking HE-VT the ''Mirka'' has no air defence, and staying in the open also invites bombers to exploit this. The HE-VT once unlocked should be the primary armament, due to a slightly greater explosive mass and decent effectiveness against planes. The rocket launcher is useful only at extremely close range and the torpedo battery is small, limited in firing arc and weak.

Captains of the Mirka should attempt to close the distance on any target and engage with their guns within 5 km for maximum effectiveness, reserving torpedoes and rockets for extreme close quarters or emergencies. Prior to unlocking HE-VT, Mirka lacks in anti air capabilities but thanks to targeting radar, Mirka can engage targets with relative ease. The HE-VT once unlocked should be the primary armament, due to a slightly greater explosive mass and better effectiveness against planes. The rocket launcher has no anti-submarine use in game but provides an instant knock-out when fired at a small vessel, it can also be used as rudimentary artillery to fire above obstacles due to the flying arc. They can be used to engage targets at distance but the recommended engagement distance should be at 3km, this is to compensate travelling speed. Torpedoes, while limited firing arc, are your main weapon against heavily armoured vessels like [[HMS Belfast]], two of them will disable the cruiser. Rockets can also be used against them since, thanks to the high explosive power, they can lit on fire all cruisers when fired at engine compartment. They will also cripple or destroy main weaponry that the 76 mm cannons may not penetrate.

The Pr. 35, or Mirka-class, was a class of light anti-submarine frigates that were built in the mid 1960s for the Soviet Navy. They were the successor to the Petya-class (Pr. 159) light frigates. The role of this ship was the same as the Petya-class, Anti Submarine Warfare and patrol in shallow waters. It featured the exact same firepower but had a change in ASW armament, like the addition of a towed sonar, and the addition of two new gas turbines.18 Mirka-class frigates were built by Yantar shipyard in Kaliningrad, between 1964 and 1966. All ships were decommissioned between 1989 and 1992. One ship is known to have rammed the USS Caron, a US Spruance-class destroyer, in the Black Sea, on February 12th, 1988. Mirka was not exported to Vietnam, India and Syria unlike the Petya.

Description

The Pr. 35 SKR-7 is a squadron rank V Soviet frigate with a battle rating of 4.3 (AB/RB/SB). It was introduced during Update 1.89 "Imperial Navy".

Survivability and armour

Armourfront / side / back
Main fire tower5 / 5 / 5 mm
Hull16 mm (steel)
Superstructure4 mm (steel)
Number of section5
Displacement1 132 t
Crew98 people

Being a light anti-submarine frigate, the Pr. 35 Mirka-class has very little substantial armour, with just 5 mm turret armour and the 15 mm splash guard for the forward turret. While these may minimize damage caused by small calibre HE rounds and splash damage from other areas being hit, they will not protect the turrets from direct fire starting at even the size of 12.7 mm machine guns. General survivability is not much better, as the primary armament is limited to two large turrets. Losing turrets is common on the Mirka and will result in your fire being halved at the least. Furthermore, the low crew count of 98 means that a very low damage threshold can be sustained on major components before the ship is destroyed. Thankfully, the Mirka has a few aces up its sleeve to counteract these issues. To begin with, the crew are very spaced out in the ship, meaning that you will most likely survive the first few salvoes. Secondly, because the hull has such a low freeboard for the majority of the ship, most of the machinery and ammunition is protected by the sea.

Overall, the ship's survivability is below average, with its low crew and few turrets being the brunt of the issue.

Mobility

Speedforward / back
AB88 / 48 km/h
RB63 / 35 km/h

Mobility is a very strong suit of the ship. Starting at 57 km/h stock, the ship lags behind destroyers and most cruisers, and cannot hold a candle to the late-game MTBs that it might face. However, of the Corvette/Frigate class, the Pr. 35 has a distinct advantage, often holding a 10 km/h advantage or more over other ships of its size. These are rarely faced, however, and as such, it cannot be expected that you will ever be leading the charge in matches. The turn radius of the ship is reasonable, however, the initial snap can be very deceiving when initiating a turn. One major issue when manoeuvring the Mirka is the existence of the hull-mounted Sonar system. This dips far below the keel of the hull and can frequently be caught on rocks. Special attention must be given when manoeuvring around shoals and beaches where the Sonar might holdfast.

Armament

Primary armament

2 х Turret2 x 76 mm/59 AK-726 automatized artillery system
Ammunition976 rounds
Vertical guidance-10° / 85°
Minimum firing elevations of SKR-7's 76 mm turrets
Main article: AK-726 (76 mm)

The primary armament of the Pr. 35 is where the ship shines. It is armed with a pair of AK-726 76 mm semi-automatic gun turrets. Each of these turrets contains two guns, firing a total of 90 rounds per minute. This rate of fire allows for the ship to dismantle any opponent vessel in seconds, from MTBs all the way up to destroyer leaders and light cruisers. These guns have very nice post-penetration effects on targets lacking armour and can be extremely dangerous should you sneak up on someone. This rate of fire comes at a price, however, and that price is two-fold. Firstly, the guns overheat quickly, barrages tend to be limited, and the guns must be watched for overheat. Secondly, the shells have a relatively short range and their effectiveness drops off quickly beyond 5 km when shells begin to miss and fire arcs become too great to regularly hit the target.

Additional armament

Setup 15 x 400 mm SET-40 torpedo
Setup 2144 x RBU-6000 mortar
Setup 35 x 400 mm SET-40 torpedo
4 x RBU-6000 mortar
Main articles: SET-40 (400 mm), RBU-6000

The Pr. 35 "Mirka" is armed with a single quintuple 406 mm torpedo launcher armed with the SET-40 lightweight anti-submarine torpedo. The launcher has very good launch angles and five torpedoes are quite reasonable however that is where the praise ends. The torpedoes have only one operational setting, with no option for upgrades and are slow. At 54 km/h a cruiser with keen eyes can outrun these torpedoes and with 8-kilometre range, they are not going to reach much past the effective range of your turrets. Worse still the torpedoes have a meek 80 kg warhead, which will not destroy ships larger than a corvette in one hit. These torpedoes have limited use in surprising unsuspecting captains should you face something armoured such as a heavy cruiser, and can be used should the main battery fall silent, however, they are unlikely to destroy anything without multiple hits and must be used at a range where they cannot be avoided easily.

The Mirka rounds off the armament with four RBU-6000 anti-submarine rocket launchers, each carrying 12 rockets to total 48. As being rockets they have a limited effective engagement range, high arcs of fire and are very hard to aim in conjunction with primary weapons, however should a small boat decide to get too close or should you decide to engage a target at point-blank range, the barrage of 25 kg warheads smashing into the superstructure and hull of the hostile ship will almost certainly cripple it, if not outright sink it. The rockets are also useful in defending a capture point as they can be lobbed over smaller islands without exposing your ship.

Radar

Radar HUD tracking a target, with firing lead indicator, distance to the target, and closing speed visible.

The vessel comes equipped with two radars:

  • MR-105 - tracking radar director, located on the main superstructure
  • Foot-N - search radar antenna, located on top of the mast

They can spot targets at a significant range and provide a lead indicator, making it very easy to destroy aircraft using HE-VT rounds, even at long range where the target might not expect accurate fire. By default, or after being destroyed and repaired, your radar may be turned off. You can turn it back on using the Switch radar search on/off control (default: Alt+R). Be aware that if the target enters the blind spot behind the vessel, radar tracking (including the lead indicator) will be lost. In engagements with planes at distances smaller than 1 km, weapons tend to overshoot even when following the target indicator. Tracking will be lost at around 14 km, and at ranges of around 10 km or more, the lock will be very unstable. The detection range is over 20 km, including shells, missiles, and other munitions in flight. Radars have only one search mode available and do not provide any assistance in detecting or engaging surface targets.

Usage in battles

The Mirka excels in close-quarter brawling with anything its shells can penetrate, especially in dispatching torpedo boats and early destroyers. This vehicle is heavily reliant on both map and BR; it will crush 3.7 and below within seconds, but against ships of 4.7 and above will struggle heavily even within its gun range. It is best not to spawn this vehicle on maps consisting of the open ocean unless you are left with no choice; due to its limited range the Mirka needs to exploit cover in order to close the gap without being targeted by guns with over twice the range. Critically, captains should avoid the wide-open ocean, as they will draw fire from targets that they cannot engage themselves. Because the guns only fire HE, captains of the Mirka should avoid engaging cruisers, as they may find penetrating and damaging the components of cruisers difficult even in close quarters.

Pr. 35 engaging an air target

Captains of the Mirka should attempt to close the distance on any target and engage with their guns within 5 km for maximum effectiveness, reserving torpedoes and rockets for extreme close quarters or emergencies. Prior to unlocking HE-VT, Mirka lacks in anti air capabilities but thanks to targeting radar, Mirka can engage targets with relative ease. The HE-VT once unlocked should be the primary armament, due to a slightly greater explosive mass and better effectiveness against planes. The rocket launcher has no anti-submarine use in game but provides an instant knock-out when fired at a small vessel, it can also be used as rudimentary artillery to fire above obstacles due to the flying arc. They can be used to engage targets at distance but the recommended engagement distance should be at 3km, this is to compensate travelling speed. Torpedoes, while limited firing arc, are your main weapon against heavily armoured vessels like HMS Belfast, two of them will disable the cruiser. Rockets can also be used against them since, thanks to the high explosive power, they can lit on fire all cruisers when fired at engine compartment. They will also cripple or destroy main weaponry that the 76 mm cannons may not penetrate.

Pros and cons

Pros:

  • Extremely high fire rate
  • Good gun handling
  • Small target to engage
  • Decent manoeuvrability
  • Main armament capable of engaging both surface and air targets
  • Can use powerful RBU rocket launcher
  • Rockets from fly faster than those equipped by Pr.159, so hitting target is easier

Cons:

  • Guns overheat quickly, and accuracy suffers massively as a result
  • Torpedoes are next to useless
  • Poor survivability
  • Two gun turrets are easily knocked out
  • No passive anti-air armament
  • Shells have a maximum range of around 6.5 km
  • Massive air intakes on rear end of the ship causes blind angle for rear turret
  • Has less rockets than Pr.159

History

The Pr. 35, or Mirka-class, was a class of light anti-submarine frigates that were built in the mid 1960s for the Soviet Navy. They were the successor to the Petya-class (Pr. 159) light frigates. The role of this ship was the same as the Petya-class, Anti Submarine Warfare and patrol in shallow waters. It featured the exact same firepower but had a change in ASW armament, like the addition of a towed sonar, and the addition of two new gas turbines.18 Mirka-class frigates were built by Yantar shipyard in Kaliningrad, between 1964 and 1966. All ships were decommissioned between 1989 and 1992. One ship is known to have rammed the USS Caron, a US Spruance-class destroyer, in the Black Sea, on February 12th, 1988. Mirka was not exported to Vietnam, India and Syria unlike the Petya.
